TypeScript Performance Monorepo Project References

We have a large PNPM monorepo with many TS projects. tsc --build and IDE responsiveness (tsserver) degrade as the repo grows.

What tuning steps actually help in practice?

Project References setup and composite usage
Avoiding path alias pitfalls
skipLibCheck, incremental trade-offs
Splitting type-heavy packages
Using --isolatedModules across workspaces

Any real-world configs to share?
